Abstract

Eksplosiv perforeringsanordning (10) for å perforere brønner (1) som har et antall av perforeringstrinn (12, 13) anordnet under hverandre, hvilke trinn hver har flere perforeringsladninger (16). Hvert perforeringstrinn har en adresserbar bryter (14) hvilken kobler detoneringsledingen gjennom i hviletilstanden og isolerer detoneringsledningen (11) i driftstilstanden og kobler detoneringsledningen til en tenningsstyreanordning (15) for vedrørende perforeringstrinn.
